WATCH- REGU LATO R.

SPECIFICATION forming part of Letters Patent No. 240,053, dated April 12, 1881.

Application filed February 4, 1881. (No model.)

To all whom it may concern:

Be it known that I, CHARLES TESKE, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in atch-Regulators;

and I do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts.

My invention relates to a mechanism to be attached to watches for the purpose of giving a very fine movement to the end of the regulator-arm, especially in a certain class of American watches, as will be hereinafter set forth.

The object of my improvement is chiefly to adapt a certain adjusting mechanism, which I have heretofore patented, to use with several classes of full-plate American watches, so that the regulating device can be readily attached to any of them without making changes in the construction of the watch and it also has for an object the improvement of some parts of the regulating device.

In the accompanying drawings, illustrating my invention, Figure 1 shows the top plate of a watch having my improvement attached. Fig. 2 is an enlarged view of my regulating device detached. Fig. 3 is a vertical longitudinal section through the regulator-arm and my improved regulating device. Fig. 4. shows the top plate of a watch as ordinarily arranged, having an are carrying a scale to adjust the regulator.

The difficulty of reconstructing any of the parts of a watch in order to attach a new and improved device for moving the regulator-arm, and the dislike of owners and manufacturers to marring the appearance of the movement by making new holes for screws and leaving the old ones exposed, showing that alterations have been made, has led me to devise a supporting-plate for my regulating mechanism which can be used without any change in the screw-holes in several classes of American watches, including all the eighteen-size fullplate American movements, which have the index screwed on the upper platcthose well known as the YValtham, Elgin, Springfield, IIL, Rockford, 111., and Hampden, Mass, movements. I accomplish this by the following construction.

A is the top plate of one variety of full-plate American watch.

B is the regulator-arm, constructed and attached in the customary manner.

0 is the scale, which is screwed to the plate under the movable end of the regulator-arm by the screws D and E, as constructed in the class of watches before named.

F is the plate of my improved regulating device for giving a fine movement to the regulator-arm. This plate is made of the following form to accommodate it to fit all the kinds of watches before named. Upon itsinneredge it is furnished with the projecting parts G and H, in which are formed the holes for the attaching-screws. The hole G is round, as commonly formed, and is adapted to lit the screw E. The hole H, however, is made in the form of an elongated slot, forthe purpose of adapt ing the plate to be attached to watches of different kinds having a different length between the serews D and E. This slot is made nearly or quite upon the arc of acircle struck from the center, upon which the regulator-arm turns, and passing through the screws D and E. The length of the slot required is about three times the diameter of the ordinary screw.

In order to attach my improved device to the plate of the watch, all that is required is to remove the scale C and screw on the plate F with the same screws. No new holes are required to be bored and no new threads cut.

At F the corner of the plate F is rounded. This is for the purpose of accommodating the form to certain classes of the \Valtham watches, in which the plate C would otherwise project over the edge of the upper plate of the movement. Theproiections from theplate C- marked F and S, for Fast and Sloware so placed as not to interfere with any part of the plate to which C is attached, nor any part of the watch-movement.

J is the adjusting-screw for moving the arm B by turning its head, as described in my previous patents. The head is furnished with a slot and holes for this purpose. The screw J turns in the standards K and L, fixed to the plate 0, and is heldfrom longitudinal movement by the head at one end and by the pin M at the other.

N is a sliding nut, which bears lightly upon the plate 0, to prevent it from turning, so that it will be carried along the screw J when the latter is turned. The nut N has a projecting flange, N, carrying the regulator-arm B by means of the pins 0 0, between which the end of the arm B is embraced and by which it is moved. These pins can be made of sufficient height to accommodate the different heights of the regulator-arm, so that one construction will answer for all the before-mentioned movements. These pins can also be made sufficiently yielding and elastic to always touch and embrace the arm B in its differentinclinations to the right or left.

By means of my present invention my improved regulating device can be made and sold as an article of trade, and can be readily attached to watches of the construction before named by any one of even ordinary skill, not requiring an expert workman nor any tools except a small screw-driver.

What I claim as my invention isv 1. The plate C, provided with the hole G and the slot H, lying in the direction of the hole G, constructed as described, and adapted to fit upon the classes of American full-plate watches, substantially as set forth.

2. The plate 0, provided with projecting parts, furnished with the hole G and slot H, lying in the direction of the hole G, and the rounded corner F, by which it is adapted to fit certain classes of watches, substantially as described.

3. The combination of the plate 0, constructed and arranged as described, and having the slotted screw-hole H, with the screws D E and plate A, of a full-plate American watch, substantially as set forth.

4:. The nut N, furnished with the pins 0 O, in combination with the adjusting-screwJ and regulator-arm B, of the ordinary construction, substantially as described.

CHARLES TESKE.
